Marcs is a reference to the French artist Marc Chagall and his close friend, the French poet Antony Apollinaire. Chagall and Apollinaire were both prominent figures in the early 20th century avant-garde art movement. They were known for their close friendship and collaboration on various projects, including the publication of Apollinaire's book of poetry, 'Alcools'. Chagall and Apollinaire were also both influential in the development of modern art, with Chagall's work often featuring vibrant colors and dreamlike imagery, while Apollinaire's poetry was characterized by its use of free verse and surrealism.
